HiT Entertainment wanted him to concentrate on Thomas alone, but it was later decided that he could also voice Toby if he wished to do so. This then snowballed because HiT wanted to have the same voices for some characters in both the UK and US versions.

Both he and Jules de Jongh voiced characters from "The Haunted Pumpkin of Sleepy Hollow".

Small said in an interview with the Sodor Island Fansite that he was a fan of the Railway Series in his youth. He said that he listened to the Johnny Morris recordings as a child.

Small and Keith Wickham previously worked together on the French television series, "Watch My Chops" (aka "Corneil & Bernie"). Wickham voiced Corneil the dog and Small voiced Bernie, his dogsitter in the English version. They also both performed Party Time during live events.
